Quality Control

Our Tetrakis(2-Mercaptoethyl)Ethylenediamine is manufactured under strict quality management systems. Every batch undergoes rigorous analytical testing, including assay by titration and impurity profile analysis by HPLC, to ensure high purity and batch-to-batch consistency. Certificates of Analysis (COA) detailing all specifications are provided and available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store under an inert atmosphere (e.g., nitrogen or argon) in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its sensitivity to oxidation and moisture, containers must be kept tightly sealed after each use to maintain product integrity.
